Virtual simulation of the biomechanics of the abdominal wall with different stoma locations
Biomedical engineering; Gastrointestinal diseases; Mathematics and computing ; Ingeniería Biomédica; Enfermedades gastrointestinales; Matemáticas e Informática ; Enginyeria Biomèdica; Malalties gastrointestinals; Matemàtiques i informàtica ; An ostomy is a surgical procedure by which an artificial opening in the abdominal wall, known as a stoma, is created. We assess the effects of stoma location on the abdominal wall mechanics. We perform three-dimensional finite element simulations on an anatomy model which was generated on the basis of medical images. Our simulation methodology is entirely based on open source software. We consider seventeen different locations for the stoma incision (trephine) and we simulate the mechanical response of the abdominal wall when an intraabdominal pressure as high as 20 kPa is applied. We focus on factors related to the risk of parastomal hernia development such as the deformation experienced by the abdominal wall, the stress levels supported by its tissues and the corresponding level of trephine enlargement. No significant dependence was found between stoma location and the levels of abdominal wall deformations or stress supported by tissues, except for the case with a stoma located on the linea alba. Trephine perimeter and area respectively increased by as much as 44% and 85%. The level of trephine deformation depends on stoma location with considerably higher trephine enlargements found in stomas laterally located with respect to the rectus abdominis muscle. ; Financial support for the current research was granted by Universitat Rovira i Virgili, project number 2018PFR-URV-B2-29.
